An educated guess is that you need the top 4 listed here: http://www.elecraft.com/K3/k3_app_notes.htm This is based on the bottom 3 which state "about 01/09/09", your S/N #3215 and a VY2SS post: "Elecraft K3 ser#3408 came into existence today September 14, 2009!" All 3 RF Board mods are easy to determine by inspection...easily accessible by removing the bottom front panel. You may also want the K3DSPLPF kit to bring your Rev C DSP board up to Rev D. See: http://www.elecraft.com/K3/mods/dsp_rev_c_information.htm ...as well as the K3SYN Stiffener Mod (fixes microphonic coupling from the speaker into the K3SYN): http://www.elecraft.com/manual/ELECRAFT%20KSYN3%20Stiffener%20Mod%20Rev%20D.pdf All of the above except the LPF kit are relatively easy to install. Unless you hear a 12 kHz artifact in your audio, you probably can skip the LPF kit which is more complex. The extended low end DSP audio mod is already in your Rev C DSP. Just to be safe, I would confirm the above with Gary@ or k3support@ elecraft.com. 73, Bill W4ZV -- View this message in context: http://elecraft.365791.n2.nabble.com/K3-mods-timeline-tp6761509p6761799.html Sent from the Elecraft mailing list archive at Nabble.com. ______________________________________________________________ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:Elecraft@mailman.qth.net This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html
